Pivoting is a technique used to rotate(transpose) rows to columns. It turns the unique values from one column in one table or table expression into multiple columns in another table. SQL Server 2005 introduced the PIVOT operator as a syntax extension for table expression in the FROM clause. P...

PIVOT carries out an aggregation and merges possible multiple rows into a single row in the output. UNPIVOT doesn't reproduce the original table-valued expression result, because rows have been merged. Also, NULL values in the input of UNPIVOT disappear in the output. When the values disappear...
You can use the PIVOT and UNPIVOT relational operators to change a table-valued expression into another table. PIVOT rotates a table-valued expression by turning the unique values from one column in the expression into multiple columns in the output. PIVOT also runs aggregations where they're req...
